We believe that the subdermal implanted microchip will
eventually be the 666 Mark of the Beast , when placed in the
right hand or forehead for all financial transactions. We also
can see that an external tattoo could be placed over the MOB (
Mark of the Beast ) . . 1. To show allegiance and loyalty to the Beast, and his
666 System
2. To show the exact location of the chip.
Tattoos are a possibility, along with the internally embedded
microchip.

Below are many good insights from many good ministries.
Each ministry is a blessing as all of us try to put the pieces of
the puzzle together. There are some paragraphs we may disagree
with in some of the articles below, but all of us agree on the
fact that the Bible is to be obeyed and Jesus is to be worshipped
alone.

External Mark This number or name is something that is visible that is
on the outside not on the inside, once taken their is no turning
back. This will be something so evident that someone would
literally have to climb over Jesus command to receive it.
Rev. 16:2 So the first angel went and poured out his bowl
upon the earth, and a foul and loathsome sore came upon the men
who had the mark of the beast and those who worshiped his
image. They will be literally tortured for doing thisSo what exactly is the Mark, It is the badge of allegiance
for the followers of Antichrist, stamped on the forehead or right
hand. The same as a scratch or etching, it is an engraving an
impress, a stamped image, an exact copy.

Robertson's Greek words says A Mark means to engrave,
used in Acts 17:29 of idolatrous images, but in Rev. it is the
brand of the beast on the right hand or on the forehead or on
both. the ancient official business documents in papyri often
have the same name and image of the Emperor, with the date as the
official stamp or seal and with the charagma as the name
of this seal. Animals and slaves were often branded with the
owners name, as Paul (Gal.6:17) bore the stigmata of Christ.
Ptolemy Philadelphus compelled some Alexandrian Jews to receive
the mark of Dionysus as his devotees (3 Maccabess 3:29). The
servants of God receive on their foreheads the stamp of the
divine seal (Rev.7:3) Some believe John gets his metaphor from
the Tephillim (phylacteries) which the Jews wore on his left hand
and forehead. At any rate, this mark of the beast
will be necessary for life and all social business relations. On
the right hand, that is plain in sight. Upon their forehead (epi
ton metapon).
Whether it is put under skin does not matter as it is clear from
the words it will be seen on the outside in some matter.

But the mark itself is a sign of allegiance, an
act of worship of Antichrist ( false Messiah). Its similarity to
wearing phylacteries in the Old Testament and Ezekiel's inkhorn
cannot be overlooked. It will be an admission that the wearer is
under the authority of Antichrist, and gives his allegiance to
his cause. We know as far back as the ancient Egyptians have
marked their bodies with tattoos, cut
marks into their skin, which is pagan ritualistic worship

So it is not hard to make a leap to having some kind of
computerized or engraved tattoo that will be a sign of allegiance
to the new world orders new leader, the Devils substitute.
Considering the OT warnings on cutting oneself or prohibitions of
tattooing, it should not surprising that one would take the mark
on their body seeing how open we are today to cut and put jewelry
and rings in unlikely places and tattoo's all over our bodies. We
are literally prepared to accept this. Today their are all kinds
of tattoos accepted and even in fashion, some quite hideous, it
is this spirit that we see moving mankind to accept a mark.http://www.letusreason.org/Proph5.htm
